Modules & VBA :: DLookup To Return A Value Starting With Specific Letter
Feb 25, 2014
I am trying to use a DLookup to search to find what block goes into the production of an item.
In a table called "dbo_vw_MCE_job_with_materials", each item contains a list of the parts which go into its production in a column titled "Expr1". However there are always more than one parts to this, with varying names.
What I am trying to do is to use a Dlookup to only return the first value which starts with B (as the block number is always the only part on the list which begins with B).
However I think as the item column contains the same item number in 8 columns, with different values in the Expr1 column, Dlookup only returns the top value "A-CF0057" (which is irrelevant as far as I am concered) - whereas I am hoping it will be able to pull the "B1499" value from the column as it is the only one starting with a B
Is there anyway to specify which value the dlookup function would return, or is there any way to apply some sort of permanent filter on my table?
I have to add an Input Mask or force the user to enter in a specified format in a text field. The condition is, text should start with "A" or "T". The complete format is A-12345-67890 or T-12345-67890.
Basically I want to get the ID (a number) from a specific record where the JOB NUMBER equals the string I have typed in to a field on the form, also called JOB NUMBER.
However, my problem is that it doesn't navigate to the record where the criteria matches, it just chooses the ID from the very first record of the table.
I have a small table, that only contains one record (and should only ever contain one record, which simply gets edited to suit once in a while).The table is called OtherRates, and the fields are as follows:
I am trying to use DLookup to return a value from the relevant field in this table, however the field to look in is a variable.The code (below) that I have tried returns an error and highlights the DLookup line,.
I have been trying to find a solution to why I can't get a Dlookup with multiple criteria to return the value I need.
Essentially I am trying to use an Order Number to find the item number which is contained within another table. However the order number has multiple lines (suffixes) which alter the item number. Therefore I am trying to have the item number be populated by the correct 'combination' of Order Number and line ("suffix").
I have managed to use the Dlookup in the after update of each box of the form separately and they retrieve values in the table correctly:
Afterupdate of main order number:
Code:
Private Sub OrderNumbertxt_AfterUpdate() ItemNumbertxt = DLookup("item", "dbo_job", "[job] = '" & Forms![**INPUT]![OrderNumbertxt] & "'") End Sub
Afterupdate of suffix:
Code:
Private Sub SuffixTxt_AfterUpdate() ItemNumbertxt = DLookup("item", "dbo_job", "[suffix] = Forms![**INPUT]![SuffixTxt]") End Sub
However when I combine them as follows in the afterupdate of the Suffix box I receive a "Run-time error '13': Type mismatch"
Code:
Private Sub SuffixTxt_AfterUpdate() ItemNumbertxt = DLookup("item", "dbo_job", ("[suffix] = Forms![**INPUT]![SuffixTxt]") And ("[job] = '" & Forms![**INPUT]![OrderNumbertxt] & "'")) End Sub
I think the reason is something to do with some being numbers and some being a combination of text and numbers (based on the replies of other topics), but have been trying to modify these slightly and can't get it to work still.
Also the Order Number is a combination of letters and numbers (normally in the form of AB12345678), the suffix is just a number between 0-9 and the Item number it finds is a combination of numbers and letters.
I am trying to make a DLookup function to return the ID number of an entry that matches 2 or 3 criteria but I am struggling to get the syntax correct for the second and third criteria.
Here is what I have so far:
1 criteria, works fine =DLookUp("[timedata]![id]","timedata", "[processdone] =" & Forms![Mainform]![p11] )
2 criteria, works fine =DLookUp("[timedata]![id]","timedata", "[processdone] = " & Forms![Mainform]![p11] & " And [timedata]![BGSnum] = 1001" )
BGSnum is a numerical value but it changes for each form I load, so what I want to do is use the form location value as the criteria.
I am trying to return a single value from a table and assign it to a string to be used later but Dlookup isnt working at all. below is the code im using and the error message im recieving is "wrong number of arguements or invalid property assignment"
Code: Sub boo() Dim result As Integer result = dlookup("Definition", "Config", "Parameter = 'Mail Folder'") End Sub
what is the best/cleanest way to return the next primary key value which is in the format yyyy-###.These are case files for the current year, ### being 3 digit number incremented by one for each new case.
I could use a function that finds the last one, checks the date, increments by one and returns it, but maybe I could use a public property or a class? I'm keen to use classes more for code maintenance.With a class then: would i create a PrimaryKey variable of the class type/object, so when I need a new key I would just type PrimaryKey.NewKey, for example?
I've inherited a few Access DB monstrosities. One of which had ODBC credentials hard coded in the MDE which I had to recently update due to some server updates. I found an unsplit version of the Access DB on a development drive (j:db...) and updated the credentials hard coded in VB and updated the linked tables from the J drive path (dev) to the K drive path (prod). I then split the DB and the MDE worked fine for me. I quickly found out that it only works fine because I had J mapped still. End users do not have the J drive mapped (development) only the K (production). Without the J drive mapped to the actual dev path the Access DB simply doesn't load. No errors.
I then tried to find any references to J in VB and fix those. At this point I can't seem to find anything else that could be referencing the J drive but still the DB will not open without J mapped.
I would like to create another field in the query using DLookup to return the value of the BrithMon.
BrithMonthID=DLookUp("MonID","tblListMons","BirthM on = Mon")
This works good if used with an unbound text box on a form, but when entered into a query expressions, an error is returned: cannot find the name 'BirthMon'
Can I used DLookUp in a Query expression to refer to another Query created field?
I have a simple UDF that takes a string and returns a variant, which is an array of strings Example Input "Brick Wall" Return value would be a variant array with first element "Brick" and and second element "Wall" Now I have a table with a field of strings, and I want to make a query that returns all the results from the function, one per line.
So if my input table looks like this
[strField] "kick the ball" "return the pass"
my query result should looks like this
[Orig] [new] "kick the ball" "kick" "kick the ball" "the" "kick the ball" "ball" "return the pass" "return" "return the pass" "the" "return the pass" "pass"
Last time I had to do something like this I used VBA exclusively, with ADO objects, but I thought a query based solution would be easier.
With my current data the largest return array size my function returns is 27 elements but I wouldn't want to rely on that number being fixed.
I have a search from that has an option group, text fields, and a checkbox where the users selects a variety of option that generates a query. If the query return at least on record a split form (form on top/datasheet on bottom) is displayed and the form has an Edit and Close button. If the query returns no records the form is still displayed except the buttons are not visible.
If I knew the result of the query and then made a decision whether to open the form or release control back to the search box that would be great. To open the form I am using VBA with the DoCmd.OpenForm(,,"MyQuery","criteria") command.I thought about using the DLookup command and evaluate the return value for null to be used to control the program flow.
I want to autofill in a text box with reference to a table I have in Access.I have the first text box that returns the first record in the table i want to get the data for with "text1 = Dlookup("numplate", "cars", "")
This returns the first record. I want the second text box to return the second number plate from the table.How can I get the second record to be returned...?
I am trying to Dcount in a report agianst a query but I need to narrow down to a specific name within the [Catgory] for example [Category] ='Allowable' How do I fit that into the statement?
Having problems with the following function to goto a specific record and return a value from a field in that record.
Code:'Public Function intFieldZConv(strICAO As String) As IntegerPrivate Function intFieldZConv() As Integer 'TEST PURPOSE ONLYDim strICAO As String 'TEST PURPOSE ONLYstrICAO = "KTCM" 'TEST PURPOSE ONLYDim cnCurrent As ADODB.ConnectionDim rsFieldInfo As ADODB.RecordsetSet cnCurrent = CurrentProject.ConnectionSet rsFieldInfo = New ADODB.RecordsetrsFieldInfo.Open "tblFieldInfo", cnCurrent, , , adCmdTable'rsFieldInfo.Index = "FieldICAO"'rsFieldInfo.Seek "=", strICAOintFieldZConv = rsFieldInfo!FieldZConvSTMsgBox intFieldZConv 'TEST PURPOSE ONLYrsFieldInfo.ClosecnCurrent.CloseSet rsFieldInfo = NothingSet cnCurrent = NothingEnd Function
strICAO is received from another function which is to be used to determine the specific record in the table "tblFieldInfo". Once that record is referenced, the value from the field "FieldZConVST" is returned.
My problem area is highlighed (index and seek) which I receive an error stating "method or data member not found". Any help would be appreciated on how to finding a specific record.
I have a large table with millions of entries. I want to run a query to return all entries that are on a Saturday. The date stored in the table though is just typical date format eg 15/11/2015.
SELECT Assets.* FROM Assets WHERE (((EXISTS (SELECT * FROM LCAMdump WHERE Assets.BarcodeNumber = LCAMdump.T_TAG )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((SELECT BuildingName FROM Building_Names WHERE ASSETS.BuildingNameID = Building_Names.BuildingNameID)=LCAMdump.BUILDING) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((Assets.FLOOR)=[LCAMdump]![FLOOR]) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((Assets.DeskLocation)=[LCAMdump]![LOCATION_SEGMENT2]) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((Assets.BuildingLocation)=[LCAMdump]![LOCATION_SEGMENT1]) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((SELECT FirstName FROM Employees WHERE Assets.EmployeeID = Employees.EmployeeID)=LCAMdump.USER_FIRST) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((SELECT LastName FROM Employees WHERE Assets.EmployeeID = Employees.EmployeeID)=LCAMdump.USER_LAST) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((SELECT SSO FROM Employees WHERE Assets.EmployeeID = Employees.EmployeeID)=LCAMdump.LOGIN_SSO) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((SELECT UserID FROM Employees WHERE Assets.EmployeeID = Employees.EmployeeID)=LCAMdump.USER_LOGIN) )) =False));
It works great returns the correct results. But I don't need everything out of Assets. I just need a few things from there and a few things from 2 other tables.
I tried this but it now gives back over 220 repeating results.
SELECT Assets.BarcodeNumber , Employees.UserID , Building_names.BuildingName, Assets.Floor , Assets.BuildingLocation , Assets.DeskLocation , Employees.FirstName , Employees.LastName , Employees.SSO FROM Assets , Employees, Building_Names WHERE (((EXISTS (SELECT * FROM LCAMdump WHERE Assets.BarcodeNumber = LCAMdump.T_TAG )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((SELECT BuildingName FROM Building_Names WHERE ASSETS.BuildingNameID = Building_Names.BuildingNameID)=LCAMdump.BUILDING) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((Assets.FLOOR)=[LCAMdump]![FLOOR]) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((Assets.DeskLocation)=[LCAMdump]![LOCATION_SEGMENT2]) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((Assets.BuildingLocation)=[LCAMdump]![LOCATION_SEGMENT1]) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((SELECT FirstName FROM Employees WHERE Assets.EmployeeID = Employees.EmployeeID)=LCAMdump.USER_FIRST) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((SELECT LastName FROM Employees WHERE Assets.EmployeeID = Employees.EmployeeID)=LCAMdump.USER_LAST) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((SELECT SSO FROM Employees WHERE Assets.EmployeeID = Employees.EmployeeID)=LCAMdump.LOGIN_SSO) )) =False)) OR (((EXISTS (SELECT * FROM LCAMdump WHERE ((SELECT UserID FROM Employees WHERE Assets.EmployeeID = Employees.EmployeeID)=LCAMdump.USER_LOGIN) )) =False));
I am sure it something simple but I am a novice at this so please help me. :D
Is there a way of importing MS Excel Spreadsheets but starting from row 8. I am now getting lots of spreadsheets but i only need data from row 8. I have to manually delete the rows and save the spreadsheet then import. Some days i can have more then 1.
I was just wondering if this is a possibility to do in one query or if it has to be run from a number of different queries.
I am currently developing a database from scratch for work (with very little Access experience).
The current query I am trying to run, if linked to a number of tables with different information.
What I am trying to do primarily is link stock to a specific "Host Name", "Serial Number" and "Part Description".
In the "Host Name" there is for example - A1-TX10-10001, B1-TX2-10004, C1-TX-10004 - The latter part of the name is a unique identifier number. The first part is the compartment in which the "stock" sits. So you may have all three components (A1-TX1, B1-TX2, C1-TX3) linked to the same unique identifier (10001 for example)
The serial numbers naturally are different for every single one and of course the srial numbers are linked to the "Part Description" - which will read something like....."C1-TX3 Transmitter", "B1-TX2 Combiner" etc.....
When I run the query like this the Host Name (which is also linked to the unique identifier on its own (10001) it returns everything under "A1-TX1-10001"
What I would ideally like to do is write a statement so that if the "Part Description" contains "A1-TX1" it will only return rows that contain "A1-TX1" in the Host Name and the same for "B1-TX2" and "C1-TX3" in the same query.
If "Host Name" contains "A1-TX1" to return "Part Description" to contain "A1-TX1"
I'm creating an accounts package..I've used access chart wizard to create a chart that shows total gross income per month.This displays correctly but the months start at January and end in December. It would be more useful if the months could start and end for the financial year. The syntax generated by access for the current implementation is:
Code: SELECT (Format([DatePaid],"MMM 'YY")),Sum([TotalPaid]) AS [SumOfTotalPaid] FROM [Q_AllCust_Gross] GROUP BY (Year([DatePaid])*12 + Month([DatePaid])-1),(Format([DatePaid],"MMM 'YY"));
How do I edit this to make say September my start date?
